Go onto steam and look how many people use Linux.
You'll be very lucky to get BG3 because 99% of the market is on Windows.
I'm not using Steam, while I play on Linux. So what does that tell you? I'm not part of those numbers. And your argument is not relevant to Larian, who were already supportive of Linux releases in the past, when Linux market was smaller than it is today. Since then it has grown. So if you think market size is the indicator, it should be better than in the past.
Also, please read what was said about Stadia above. It addresses the needed market size for decision making. I.e. Larian are already making the Linux version for Stadia. The question is about releasing it for desktop users, not about "whether to make it or not".
